Free memory on an HP-41CX... - Andreas Terzis - 03-16-2006 Most of you would have noticed my multiple posts about those 'nice' sellers on eBay recently. In any event, I purchased an HP-41CX that has a 'SIZE 100' set and shows '.END. REG 169' in 'PROGRAM' mode. My HP-41C with four memory modules shows 219 registers. I turn the CX on and off a few times and then it has 156 registers of program memory!!! What is going on here? Any insights?

Re: Free memory on an HP-41CX... - Andreas Terzis - 03-17-2006 It's a Halfnut. I reset it and after that it didn't do it again, after 20 times of turning it on and off. It has an Advantage module plugged in it as well as a 'Dbl Mem' module. Do you know of any diagnostics to try?

Re: Free memory on an HP-41CX... - Andreas Terzis - 03-17-2006 Marcus, Other stories: HP-41's on eBay - Karl Schneider - 03-20-2006 Hello, Andreas --
Quote: I sympathize with your difficulties pertaining to your halfnut 41CX, but it should be noted that many eBay sellers don't really know much about the HP calculators they offer. They may not even be aware of problems they should divulge. A seller's expertise can usually be deduced reasonably well from the auction description. Failure or refusal to answer questions gives even more insight. Some sellers do know about their product, and are also very upstanding. You can expect to pay more to win their auctions, because other buyers recognize it. My personal experience buying two fullnut 41's through eBay has worked out fairly well, all things considered.
The moral here is "caveat emptor" -- let the buyer beware (and assume some risk of additional expense if things aren't quite perfect). Regards, -- KS
